The download, upload and ping test will be performed to the closest server available near your location. This will mean that test will also be influenced by other factors such as quality of interconnection of KDDI with Internet backbone. This test is more relevant to assess real Internet connection quality than ISP sponsored test since those typically test against a server within the ISP and do not test real Internet speed.
